Which hormone secreted by the adrenal cortex regulates metabolism?

The hormone secreted by the adrenal cortex that regulates metabolism is aldosterone. This hormone is part of the mineralocorticoid family and plays a crucial role in regulating sodium and potassium levels in the blood, which indirectly affects blood pressure and fluid balance. While aldosterone is best known for its role in electrolyte balance, it also contributes to metabolic processes by influencing how the body manages minerals that are essential for metabolic activity.

The other terms listed do not refer to hormones associated with metabolic regulation. Acidosis pertains to an increase in acidity within the body, specifically referring to a medical condition rather than a hormone. Hemophilia is a genetic disorder that affects blood clotting, and acromion is a bony prominence on the shoulder blade, not a hormone. Thus, the correct association of aldosterone with metabolic regulation makes it the appropriate answer.
